T 0 aZZ whom 'Zt magl/ concern.' f

Be it known that we, BURT A. MONTGOM- nnr, SIDNEY SMITH, and Enwann Von GUN- inN, citizens of the United States, residing at Akron, in the county of Summit and State or' Ohio, have invented certain new and user'nl Improvements in Window- Screens: and we do declare the following to be a full, clear, and` exact description ot' the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to improvements in window screens and more particularly to those of the class which are connected to the window sash to open and close therewith.

rl'he object of the invention is to provide a simply constructed'and efficient screen of this character which will automatically wind up on .the closing of the window and may be readily connected or disconnected from the sash.

Another object is to so construct a screen of this character that it mty be engaged and Supported by its inclosing casing when disengaged from the sash ready for connection with the sash when desired.

1i.Vith the above and othervobjects in view, the invention consists of certain novel features of construction, combination and arrangement ol parts hereinafter more fully described and claimed.

1n the accompanying drawings: Figure 1 represents a front elevation ot a window equipped with this improved screen shown attached to the sash and in a partially raised position; Fig. 2 is a longitudinal section taken on the line 2 oi' Fig. 1; Fig. 3 is a detail perspective view or' one of the screen guides which is designed to be at tachcc. Fig. ai is a similar view of the bottom plate of the screen inclosing casing; Fig. 5 is a similar view ot the casing cover; Fig. 6 is a similar view of the means which is carried by the upper end of the screen lor connectingl it either with the window sash or with its casing; Fig. 7 is a similar view ot the screen attaching member carried b v the window sash.

1n the embodiment illustrated, a window frame F ot ordinary construction is shown having secured to the inner faces of the opposite side members thereoi` screen guides 1 and Q which are similar in construction and hence one only will be described in detail.

Each ofthese guides is here hown formed from a single plate of metal folded longitudinally upon itself intermediately ot' its width to form a laterally projecting rib 3 and which is provided on one edge with a flange i spaced from and arranged pa 1allel with the rib to form a groove 5 to receive and lguide the screen proper to be described. At tie other side of the rib 3 the plate extends at r d it angles to said rib and is apertured at longitudinally spaced intervals to provide an attaching flange 7 tor connecting it to the frame. An extension 6 is Jformed on the lower end of each guide and is in the form of a continuation of the flange Ll and the spacer el which is arranged between said flange and the rib 3. This extension G is designed to form a stop for the screen to he described should it become accidentally7 disengaged from its casing or the sash and thus prevent said screen from swinging out ot the window. lt is of course understood that one of these stops is provided at each side of the window frame as is shown clearly in Fig. 1.

Secured to the window sill S is a screen casing here shown constructed of a base plate 8 which extends across the entire width ofthe window and is provided at its opposite ends with upstanding bearing plates 9 which are designed to receive the pintles of the screen roller 10, said roller being in the form of an ordinary window shade roller having a round pintle at one end for engaging a round aperture 11 in one bearing' memberv and a square pintle at the opposite end,

not shown. for engaging a square aperture 12 in the other bearing plate 9. rl`his oase plate 8 is provided at its rear edge with an upstanding flange 13 having cut out portions 1l atlongitudinally spaced intervals and opposite said rec cs or cut out portions 14 are laterally projecting apertured ears 15 for the passage oi fastening elements for connecting the base plate to the window sill, said ears being here sho'f'nn struck out of thefiange 13. At the opposite edge of the base plate 8 are formed two pairs ot hinge knuckles 16 which are designed to receive cooperating knuckles 17 carried by the casing" cover 18. said knuckles being connected by the usual pintles not shown. This casing cover 1S is here shown semicvlindrical in f angular lugs 20 are formed at opposite ends l of the casing-cover 18 f plates 9 at the opposite ends of the base plate frame. This. attaching .Width of .the

8, saidV bearing .plates apertures 2l arranged apertures vin the lugs .2O when the cover is in closed position.

Secured to the inner face of the lower rail R ofthe lower Window sash s is a screen attaching plate 22 here shown in the forni of a metal strip 'which is designed for engagei'nent by the screen Ato be. described. This plate is attachcd'fto the rail R by any suitable means and extendssubstantially7 across the entire sash, the lip 23 being offset from the sash a suflicient distance to provide for the insertion between it and the sash of the 4coperating screen member to bc described.

A strip of flexible screen fabric 25 is secured at one end tothe spring roller 10 being provided with asing "and a reinforcing and attaching member 2G is'fastened to the free end of said screen fab ric and is of ra length corresponding to the width of .the screen and to the distance between the side members of the frame., the ends of said member being designed to travel in the grooves 5 formed in the guides lwvhich are secured to the side rails of the member which is shown in' detail in Fig. 46, is constructed from a metal plate folded longitudinally midway its ends with'` the side 1nembers.27 and 28 thereofI spaced apart a snflicient distance to receive-'between them the free end of the screen fabric which is secured therebetween by clamping,riveting or in any other suit-able manner.

and 30 are bent `from said members 29 and 30 to form atproximity thereto as' This plate is then folded upwardly against the outer faces of theimembers 2T and 28 and'arranged in close shown in Figs. 2 and 6 and the edges ofthese upbent members 29 downwardly and spaced taching hook-lilie flanges 3l and 32, said flanges' being here shown terminating at` points spaced from A their opposite ends atthe ends of the .folded members to provide ample space between them as the ends of said members are-designed to slidevin the Ygrooves 5 when it is desirable that the attaching flanges should not interfere with this sliding` flange 32 which is disposed on theinner face of' the screen isdesigned to hook over and engage the npstanding flange 19 on the casing cover 18 when the screen is detached from the sash to prevent 'this end of' the screen from Winding up Within the casing and to adapt it to be readily accessible for use when desired. disposed at the other side of the member 26 -is designed to hook over and engage the lip 65.

23 of the plate .22 which-is attached to the to register with the having an outstriuik lip 23` vious that this screen movement.' The hook-shaped able in said frame and The flange Blivhich is arnese sash .s and thereby reliably connect the screen with the sash to adapt it Ato be raised and lowered on the raising and lowering of the sash.- From an inspection of Figs. l and 2, it will be obvious that the rib 3 terminates above the casing 18 so that when the flange 32 on the screen is engaged with the flange 19 on the casing, the ends of the member 26 will be disconnected from the guides l and be thus disposed out of' the path of the win-- dow sash permitting it to be raised and low,- ered `freely. The plate 22 carrying the vattaching lip 23 is so disposed that when the member 26 on the free end of the screen is engaged with said plate, the ends of said member will be arranged at rthelovver ends and within the ygrooves 5 of' the guides l so that when the sash is raised7 the screen Will move upwardly with these ends traveling in said grooves and thus prevent all possi-` bility of lateral movement. of the screen..

in upstanding hook 33 rises from the member 26 preferably at a point midway the ends thereofv and is designed as a handle to facilitate the engagement and disengagement of the screen either with the casing flange l0 or with the sash plate 22 as may be desired. l l
